We tested zaps on this note… we made six attempts to⚡zap this note, at craig@zap.bitcoin-cats.ca, over a period of about 1 hour. In each case, we found that your lightning address server did not respond correctly. (The failure point was when we did a GET request to your specified callback URL: https://zap.bitcoin-cats.ca/BTC/UILNURL/pay/lnaddress/Craig ). Your server did not produce an invoice, thus the zap failed. The error we got was "Lightning node could not generate invoice with description hash: The HTTP status code of the response was not expected (500).". You might want to look into using a cloud-based Lightning node which is optimized for Nostr zaps, to get your zaps working.
